National Parks Create 10 Times the Dollars They Cost

In 2010 the federal government gave the National Park Service
$2.7 billion and the return on investment was $31 billion and 258,400
jobs. According to a just-out, peer-reviewed study on the
economic value of the NPS, most of the revenue was generated by lodging
and food bought by visitors, who totaled a whopping 281 million — the
equivalent of 90 percent of the U.S. population.
